Abstract: A cooling system for a liquid-cooled internal combustion engine for a motor vehicle comprises a first device (23), which responds to the temperature of the coolant for the engine flowing through a first section of a coolant line (4') to the radiator. Provided in addition is a second device (11, 21) which is actuated in dependence on the first device (23) in order to control the flow of coolant through a second section (12) of the coolant line, this second section being situated downstream of the first section and upstream of a coolant pump. The second device is designed and arranged in such a way that it blocks the flow of coolant through the second section (12) in low-load operation and zero-load operation of the engine if the coolant temperature is between a first predetermined level and a second, higher predetermined level and enables flow of coolant through the second section (12) in all operating ranges of the engine if the coolant temperature is above the second predetermined level. This results in a considerable improvement in fuel consumption and the hydrocarbon content of the exhaust gas. <IMAGE>
Patent DE-3303319-A1 (DE)
IPC: B23Q37/00
Filed: 1983-02-01
Abstract: An apparatus for working a elongated angle-iron workpiece having a pair of nonparallel flanges at least one of which is to be drilled has a transport unit for displacing the workpiece longitudinally through a working station and a support in the station for holding the workpiece with the one flange forming an acute angle with the horizontal. A drilling unit including a drilling tool can move horizontally in the station transverse to the workpiece and transverse to the workpiece and at the acute angle to the horizontal perpendicularly through the one flange. To obtain a given displacement along the workpiece flange, the carriage supporting the drill unit is moved horizontally through a horizontal distance equal to the desired displacement times the secant of the angle that the flange forms with the horizontal. The drilling tool can be moved perpendicularly of the one flange during displacement of the carriage through the horizontal distance through a distance equal to the predetermined distance multiplied by the tangent of the acute angle the one flange forms with the horizontal so the drilling tool does not change spacing from the one flange during horizontal adjustment.

Abstract: The invention relates to a device for covering a window or the like from the outside with laterally guided and vertically movable elements, which in the protection position are arranged above and below the wall opening in such a manner that they bring about an additional effective heat insulation. In the covering position, the device is placed in front of a window and, in particular in the night hours, the heat loss through the window is considerably reduced. The subject of the invention makes it possible to save heat energy with relatively low outlay and moreover contributes to increased living comfort by improving the room climate and by increasing the noise protection. In winter, the device serves for protection against heat loss, in summer for protection against heating up by the sun. Additional means for setting out the plates make possible awning-like shading of the window openings. Overheating of the rooms exposed to solar radiation is avoided with the aid of the device used as shading by separate rear ventilation openings so that there is no heat build-up between covering device and window when the window is closed. In summer, ventilation of the room is also possible during night hours with the window open without burglar prevention being lost.

Title: Process for the reoxidation of dyeings using sulphur dyestuffs
Inventor: BERNHARDT HEINRICH
IPC: D06P1/22
Filed: 1983-04-02
Abstract: The reoxidation of sulphur dyestuffs in an acidic medium is associated with disadvantages, such as environmental pollution, risk of corrosion to machines etc. Oxidation in an alkaline medium may not have these disadvantages, but it is again more poorly controllable (pH dependence of colour shade constancy). According to the invention, these difficulties are removed if the textile material containing cellulose fibres and with the sulphur dyestuffs applied and fixed thereto present in the reduced form is subjected to dyestuff development by the oxidative effect of sodium N-chloro-p-toluenesulphonamide (chloramine-T) under alkaline conditions. This can be carried out both continuously and batchwise.
